Dynamic LSP Provisioning in Overlay, Augmented, and Peer Architectures for IP/MPLS Over WDM Networks
Overview This paper considers an IP/MPLS over WDM network, in which Label Switched Routers (LSRs) in the IP/MPLS layer are interconnected through Optical cross-Connects (OXCs) in the optical core network (WDM layer) providing an end-to-end wavelength routing capability. This paper studies a dynamic Label Switched Path (LSP) provisioning problem for the three different network models of the IP/MPLS over WDM network, namely, Overlay, Augmented, and Peer models. The paper proposed an algorithm, called MLH OVLY for the overlay model, in which a network finds a path with the minimum number of logical hops for an LSP request. The paper also proposes, for the augmented model, a simple and efficient dynamic LSP provisioning algorithm, called CAPA AUG, utilizing summarized capacity information from the WDM layer.
